Steel vs Aluminium Roof Bars: Which Should You Choose?

When it comes to choosing the right roof bars, one of the first decisions is steel vs aluminium. Both materials do the job — but depending on your vehicle, load, and usage, one might be the better choice.

Here’s a full breakdown to help you decide.

🛠️ What Do Roof Bars Actually Do?

They're essential if you need extra storage, plan on adventure travel, or simply want a more versatile setup.
